Review on 📐 Calculated Industries 6135 Scale Master Pro XE - Advanced Digital Plan Measure for Accurate Estimating on Printed Blueprints, 91 US Imperial and Metric Scales, 10 Custom Scaling Options for Out of Measure Plans by Jeff Labore

It's really great because it can be used on house plans, lot plans and even Rand McNally maps. If I wanted to improve it, I would (1) make the wheel pressure adjustable for different surfaces. To do this, you need a perfectly flat, smooth surface and paper. Scale creases, (2) add light so I can see the lines more clearly when it's on the surface I'm measuring, and (3) give better directions. It took me quite a while to set my own standards. I tried at least a dozen times over the course of 30 minutes before it finally worked. I'm not an engineer or IT professional, but I think the instructions are written for people with those skills. But like I said, I finally got it.
